Influxdb system/internal logs are not showing in local timezone

__Steps to reproduce:__
List the minimal actions needed to reproduce the behavior.

1. ... Bring-up InfluxDB(1.7.3) pods with k8s(1.16.3)
2. ... Do kubectl logs -f , see the logs are coming in UTC.

__Expected behavior:__
Logs should come in local timezone of hosts

__Actual behavior:__
I've mounted influxdb pod's /etc/localtime to timezone, http access logs are coming properly i.e in locatimezone but influxdb structure logging not.

ex:
Structure logging
ts=2020-08-12T17:01:44.902894Z lvl=info msg="Executing query" log_id=0O_uQ7iW000 service=query query="SELECT * FROM cpu./.*/ WHERE resourceID = 'y' AND resourceType = 'x' AND time >= now() - 5m ORDER BY DESC LIMIT 1"

Http access

__Environment info:__

* System info: Run `uname -srm` and copy the output here
`Linux 4.4.0-131-generic x86_64`
* InfluxDB version: Run `influxd version` and copy the output here
`InfluxDB v1.7.3 (git: 1.7 698dbc789aff13c2678357a6b93ff73dd7136571)`
* Other relevant environment details: Container runtime, disk info, etc
__Config:__
[influxconfig.txt](https://github.com/influxdata/influxdb/files/5080310/influxconfig.txt)

__Logs:__
Include snippet of errors in log.

__Performance:__
Generate profiles with the following commands for bugs related to performance, locking, out of memory (OOM), etc.

```sh
# Commands should be run when the bug is actively happening.
# Note: This command will run for at least 30 seconds.
curl -o profiles.tar.gz "http://localhost:8086/debug/pprof/all?cpu=true"
curl -o vars.txt "http://localhost:8086/debug/vars"
iostat -xd 1 30 > iostat.txt
# Attach the `profiles.tar.gz`, `vars.txt`, and `iostat.txt` output files.
```

Reproduce the behavior with the listed InfluxDB 1.7.3 pods using `kubectl logs -f ` and compare the structured logging output with the HTTP access logs. Review the linked config and verify that the structured logs honor the host timezone while preserving the expected UTC-versus-local behavior.
